Trailing Suction Hopper Dredgers


A trailing suction hopper dredger operates very much like a floating vacuum cleaner. With a single or twin proboscis-like suction pipes, it pumps up materials from the sea floor and discharges them into a storage compartment, or hopper. On completion of loading the dredger sails to the disposal site where the cargo can be discharged, either by opening the doors or valves in the hopper bottom, by using the dredging pump to deliver to a shore pipeline, or directly to shore by using a special bow jet. This last technique is known as rainbowing.

Via Pruned, which also provides a link to this lifetime field list of geologic sites and experiences which I would love to complete. Somehow I think that will never happen...

I just wanted to say a few things about your blog.
It's amazing, been one of my favorites since i wound it while searching for photographs of Pripyat! a source of inspiration for me and my works. I do photography and all sorts of drawing. I click my RSS-reader once in a while to see for updates. Thank you for the work you are doing, this is what we people live for. To share things among us. Showing other people your interests and share your passion to art, that sure is something.

Sorry for my bad english, i'm from finland.
Thanks again for this blog, and best of luck with it.
